• Web: web-arabic-2005, web-indochina
• Social-Facebook: socfb-UCSC68, socfb-UC64, socfb-Middlebury45
• Tags: tags-ask-ubuntu, tags-math-sx
• Road Networks: roadNet-PA, roadNet-CA, roadNet-TX

Preprocessed versions are included. If you need the original data, refer to the original sources:

Explanation

Main Codes (dgraphlet)

These files are used to execute the EDGE algorithm:

• d2s3.cpp: Counts $(2,3)$-graphlets (distance up to 2, size 3 graphlets).

• d2s3_b1.cpp: Baseline version 1 for counting $(2,3)$-graphlets (EDGE-D2 in the paper).

• d2s3_b2.cpp: Baseline version 2 for counting $(2,3)$-graphlets (EDGE-D in the paper).

• d3s3.cpp: Counts $(3,3)$-graphlets (distance up to 3, size 3 graphlets).

• d3s3_b1.cpp: Baseline version 1 for counting $(3,3)$-graphlets (EDGE-D2 in the paper).

• d3s3_b2.cpp: Baseline version 2 for counting $(3,3)$-graphlets (EDGE-D in the paper).

• d2s4.cpp: Counts $(2,4)$-graphlets (distance up to 2, size 4 graphlets).

Utility Codes

These are supporting codes for the main execution (constructing $d$-edge, $d$-graph, $d$-DAG...). Some construction code is based on the existing code available here of the paper: ESCAPE: Efficiently Counting All 5-Vertex Subgraphs.

Run Instructions

Input File Format

Currently, we only support the Matrix Market Coordinate Format (symmetric). We will update soon to support all datatypes. For more details, see: http://math.nist.gov/MatrixMarket/formats.html#MMformat.

Main Commands

1. Navigate to the dgraphlet folder:

   cd dgraphlet

2. Choose the $(d,s)$-graphlet to count (e.g., for $(2,3)$-graphlets, use d2s3.cpp).
3. Use the Makefile to compile:

   make

4. Run the executable:

   ./[filename].cpp ../data/[dataset].mtx -n

Here, n represents the number of threads you wish to use for processing.

Example command for running the $(2,3)$-graphlet on the ca-HepTh dataset using 6 threads:

./d2s3.cpp ../data/ca-HepTh.mtx -6
